Document Type and Number:
Japanese Patent JP2592451
Kind Code:
B2
Abstract:
A brake band drum for a planetary gear-type automatic transmission in which a clutch is formed inside a press-manufactured planetary gear input member coupled to a press-manufactured clutch cylinder and one member of a planetary gear mechanism, and a band brake is arranged on the outer peripheral side of the clutch cylinder or planetary gear input member, characterized in that the clutch cylinder or planetary gear input member is fitted by being splined, and an engaging surface of the band brake is formed on an outer peripheral surface of the clutch cylinder or planetary gear input member. Thus, the brake band drum is formed by fitting the brake band drum and clutch cylinder together. This makes it possible to dispense with electron beam welding. As a result, costs and weight can be reduced.
